The Amazing Human Body
Text and photos WINNIE LEUNG
Your body is made of trillions of tiny life units called cells. Cells of
the same type form tissues, tissues form organs, and related organs
link together to form different systems. The body is like a complicated
machine, and many systems work together to keep it running smoothly.
Bones, muscles, nerves, organs, blood – these are all parts of the body
systems that keep you breathing, moving, standing, thinking and growing.
MUSCLES
Every time you move, you need your muscles.
We even depend on them to sit still – without
them, we’d slump over. Muscles are bundles
of fibres that tense and relax to move different
body parts. Some are voluntary muscles, which
you can control, and others, such as your
heart, are involuntary and work automatically.
THE SKELETON
A skeleton made of 206
bones supports the
human body. It is a strong
framework that acts as
an anchor for muscles,
skin and other tissues
while also protecting soft
internal organs like the
brain and heart. Bones
are linked together by a
rubbery material called
cartilage, and joints allow
the bones to move.
